Diagnostic Test & Treatment
Implantable Loop Recorder (ILR)
An implantable loop recorder is a small device used to detect and record abnormal heart rhythms that occur infrequently. It is especially useful for diagnosing the cause of unexplained fainting spells, or for excluding a rhythm disorder.
01Why It’s Done
Dr Lee may recommend this for patients with:
- Investigating infrequent palpitations
- Diagnosing the cause of unexplained blackouts or fainting
- Long-term monitoring for atrial fibrillation
02How It Works
- A device smaller than a USB drive is inserted just beneath the skin of the chest under local anaesthetic.
- It automatically records abnormal heart rhythms.
- You or a caregiver can also activate it when symptoms occur.
- Data is downloaded in clinic or sent via a remote monitor; the battery lasts over 18 months.
03Duration, Recovery & What To Expect
Insertion is a brief procedure under local anaesthetic with minimal downtime. The device monitors quietly in the background of daily life.
